Visual Corona Inception Voltage Calculator
Estimate the corona inception voltage using Peek's empirical relation.
Formula (for a bare conductor in air):
\[
V_{ci} = 2110\, m_0\, \delta\, r \ln\left(\frac{D}{r}\right)
\]
where \(r\) and \(D\) are in meters (converted to cm internally), \(V_{ci}\) is in kilovolts.
* Enter the conductor radius, spacing (both in m), air density factor (δ), and surface condition factor (m₀).
Step 1: Enter Parameters
Example: 0.01 m (1 cm)
Example: 0.1 m (10 cm)
Typically 1 under standard conditions.
Typically 1 for smooth conductors.
